DSPPGMREF will tell you only some of the information you need to
understand about file usage. Many midrange shops have a cross reference
tool like Hawkeye or TOTAL which will find these references in a way
that a simple DSPPGMREF or a scan with PDM can't. Ask your system admin
if such a tool is installed on your machine. It might save you a lot of
work.
